Schematic of the Measuring Method (IMAGE) Forschungszentrum Juelich Caption This is a schematic of the measuring method: the tip of the in situ electrochemical atomic force microscope scans the surface of the iron electrode. Laser-beam deflection reveals spatial irregularities, which can be compared to each other over the course of several cycles. Credit Forschungszentrum Jülich / H.
